| 1 | Antioxidant activity and identification of bioactive compounds from leaves of Anthocephalus cadamba by ultra-performance liquid chromatography/electrospray ionization quadrupole time of flight mass spectrometry显示文摘Objective:To evaluate the antioxidant potential of different extract/fractions of Anthocephalus cadamba(A.cadamba)(Roxb.) Miq.(Rubiaceae) and study the tentative identification of their active constituents.Methods:The extract/fractions were screened for antioxidant activity using various in vitro assays viz.DPPH assay,ABTS assay,superoxide anion radical scavenging assay, reducing power assay and plasmid DNA nicking assay.Total phenolic content of extract/fractions was determined by colorimetric method.An ultra-performance LC-electrospray-quadrupoletime of flight mass spectrometry method was used to analyse the active constituents of extract/ fractions of A.cadamba.Results:The ethyl acetate fraction was found to be most active fraction in all the assays as compared to other extract/fractions.The IC50 value of ethyl acetate fraction (ETAC fraction) was 21.24μg/mL,1.12μg/mL,9.68μg/mL and S7.81μg/mL in DPPH assay, ABTS assay,reducing power assay and superoxide scavenging assay respectively.All the extract/ fractions also showed the potential to protect the plasmid DNA(pBR322) against the attack of hydroxyl radicals generated by Fenton’s reagent.The bioactive compounds were identified by UPLC-ESI-QTOF-MS,by comparing the mass andλmax with literature values.Conclusions:The potential of the extract/fractions to scavenge different free radicals in different systems indicated that they may be useful therapeutic agents for treating radical-related pathologic damage. | Madhu Chandel Upendra Sharma Neeraj Kumar Bikram Singh Satwinderjeet Kaur | 2012 | Asian Pacific Journal of Tropical Medicine2012,5,12: | 6 |
| 2 | Who benefits from percutaneous closure of patent foramen ovale vs medical therapy for stroke prevention? In-depth and updated metaanalysis of randomized trials显示文摘BACKGROUND A few randomized clinical trials(RCT) and their meta-analyses have found patent foramen ovale closure(PFOC) to be beneficial in prevention of stroke compared to medical therapy. Whether the benefit is extended across all groups of patients remains unclear.AIM To evaluate the efficacy and safety of PFOC vs medical therapy in different groups of patients presenting with stroke, we performed this meta-analysis of RCTs.METHODS Electronic search of PubMed, EMBASE, Cochrane Central, CINAHL and ProQuest Central and manual search were performed from inception through September 2018 for RCTs. Ischemic stroke(IS), transient ischemic attack(TIA), a composite of IS, TIA and systemic embolism(SE), mortality, major bleeding,atrial fibrillation(AF) and procedural complications were the major outcomes.Random-effects model was used to perform analyses.RESULTS Meta-analysis of 6 RCTs including 3560 patients showed that the PFOC,compared to medical therapy reduced the risk of IS [odds ratio: 0.34; 95%confidence interval: 0.15-0.78; P = 0.01] and the composite of IS, TIA and SE [0.55(0.32-0.93); P = 0.02] and increased the AF risk [4.79(2.35-9.77); P < 0.0001]. No statistical difference was observed in the risk of TIA [0.86(0.54-1.38); P = 0.54],mortality [0.74(0.28-1.93); P = 0.53] and major bleeding [0.81(0.42-1.56); P = 0.53]between two strategies. Subgroup analyses showed that compared to medical therapy, PFOC reduced the risk of stroke in persons who were males, ≤ 45 years of age and had large shunt or atrial septal aneurysm.CONCLUSION In certain groups of patients presenting with stroke, PFOC is beneficial in preventing future stroke compared to medical therapy. | Khagendra Dahal Adil Yousuf Hussam Watti Brannen Liang Sharan Sharma Jharendra Rijal Pavan Katikaneni Kalgi Modi Neeraj TANDon Michael Azrin Juyong Lee | 2019 | World Journal of Cardiology2019,11,4: | 4 |

| 15 | Physical and biochemical changes in ultra-rapid air chilled broiler muscle and quality of marinated chicken breast filets显示文摘The effect of ultra-rapid chilling in air at-20℃ over water-immersion chilling on broiler carcasses was investigated for physical and biochemical attributes.Forty-eight eviscerated carcasses were divided into two groups,one group were subjected to air chilling and other to water-immersion chilling,and samples were drawn at time periods of 1,3 and 24 h post-chill to analyze for pH,ratios of adenine:inosine nucleotide(R-values),expressible moisture,cook yield,tenderness and color.Ultra-rapid air chilled carcasses showed significant differences(P<0.05)in pH,expressible moisture and cook yield at chosen post-chill time intervals over the carcasses chilled using water-immersion technique.It was concluded that air chilled carcasses had higher pH and expressible moisture,but the R-values,and shear values did not show significant differences,and only slight difference in color of carcasses processed by the two chilling methods.In a separate experiment with 108 commercially processed carcasses,quality attributes of pre-rigor marinated breast filets were studied after subjecting the carcasses to air chilling and water-immersion chilling.Twelve filets from air and water chilled carcass aged for 1,3,and 24 h were tumble marinated for 25 min in a Sodium Tri Polyphosphate(STPP)and NaCl solution with different pick up levels of 10,15 and 20%.After measuring marinade absorption,filets were aged at 2℃ for 24 h.No differences were observed between the air and water chilling treatments in terms of marinade retention at different marinade target levels(10,15 and 20%)and time intervals(24,27 and 47 h)but cook yield of air chilled marinated fillet was higher.In conclusion,processors using further-processing operations that debone meat may find that AC to be more suitable alternative for cooling poultry carcasses because fillet color,marination yield,and tenderness were not affected,but cook yield was improved. | Rakesh K.Singh Neeraj Sharma | 2022 | Food Bioscience2022,46,2: | 1 |

| 18 | Kikuchi-Fujimoto disease:A comprehensive review显示文摘Kikuchi-Fujimoto disease,a rare form of necrotizing lymphadenitis,is an uncommon,benign,self-limiting disorder of obscure etiology.It affects mostly young adults of both genders.Clinically,it presents with fever and lymphadenopathy of a firm to rubbery consistency frequently involving cervical lymph nodes while weight loss,splenomegaly,leucopenia,and elevated erythrocyte sedimentation rate feature in severely affected patients.Cutaneous involvement occurs in about 30%-40%of cases as facial erythema and nonspecific erythematous papules,plaques,acneiform or morbilliform lesions of great histologic heterogeneity.Both Kikuchi-Fujimoto disease and systemic lupus erythematosus share an obscure and complex relationship as systemic lupus erythematosus may occasionally precede,develop subsequently,or sometimes be associated concurrently with Kikuchi-Fujimoto disease.It is often mistaken for non-Hodgkin lymphoma while lupus lymphadenitis,cat-scratch disease,Sweet’s syndrome,Still’s disease,drug eruptions,infectious mononucleosis,and viral or tubercular lymphadenitis are other common differentials.Fine needle aspiration cytology mostly has features of nonspecific reactive lymphadenitis and immunohistochemistry studies usually show variable features of uncertain diagnostic value.Since its diagnosis is exclusively from histopathology,it needs to be evaluated more carefully;an early lymph node biopsy will obviate the need for unnecessary investigations and therapeutic trials.Its treatment with systemic corticosteroids,hydroxychloroquine,or antimicrobial agents mostly remains empirical.The article reviews clinicoepidemiological,diagnostic,and management aspects of KFD from the perspective of practicing clinicians. | Vikram K Mahajan Vikas Sharma Neeraj Sharma Ritu Rani | 2023 | World Journal of Clinical Cases2023,11,16: | 1 |
